Definitions

  • the present invention relates to the ground connection of electric traction motor vehicles, in particular their motorized wheels.
  • the term “motorized hub” is used to designate the mechanical assembly comprising the hub, the hub-carrier, the guiding of the hub relative to the hub-carrier, the electric motor and the braking means of the hub. .

  • the guiding rigidity of such a design proves insufficient.
  • the hub is rotating around a rocket, said rocket passing through the plane of the brake disk.
  • the rigidity of this guidance is also insufficient because of the long length of the rocket.
  • the hub is rotating in a bore of the housing but the brake clamp is this time maintained by the suspension arm and not by the housing.
  • the invention therefore aims to improve motorized hubs of this type to make them even more efficient, for example by making them more rigid and / or more compact and / or lighter.
  • the invention therefore relates to a motorized hub for a motor vehicle with electric traction, said motorized hub comprising a hub for receiving a wheel, the hub being rotatably mounted relative to a hub carrier according to a hub axis, the motorized hub comprising an electric traction machine, the electric machine comprising an outer stator connected to the hub carrier and an inner rotor whose axis of rotation is distant from the hub axle, the motorized hub comprising reduction means acting between the shaft the rotor of the electric machine and the hub, the motorized hub comprising means for braking by dry friction, a brake rotor (12) cooled by the ambient air being secured to the hub in rotation by means of a shaft brake rotor (76) being axially disposed on the inner side of the vehicle with respect to said hub, the rotor shaft of the electric machine being placed radially out of the brake rotor and extending axially from the reduction means to the interior of the vehicle, the reduction means comprising a driving pinion (42) connected to the rotor of the

The front of the vehicle is then to the left of the figure 1 . It is well understood that the motorized hub according to the invention can also be combined with other types of front or rear suspension system such as semi-trailing arm systems, multi-arm systems or MacPherson or pseudo-systems.
